question on reverting back to stock - T-Mobile LG G2x

so I used this thread http://forum.xda-developers.com/showthread.php?t=1048274 to attempt and posted my question in the thread but to my knowledge answers dont come at your request sometimes.
I downloaded,extracted it, placed it in the external sd: clockworkmod/backup folder
and when i select restore I get md5 sums mismatched
I've downloaded it a few times and tried it on a different sdcard.
I've downloaded it to the exact spot it needs to be and then restored and no go...
so I just want to see if someone has a theory to solve the issue and leave the thread here for some one to search so they can find it

I got it no worried it was like the 7th download from a PC getting 14mb down no clue what was causing it but, maybe someone later on will shed some light on it.

[Q] Please help!

I seem to have temporarily bricked my gtab. When attempting to nvflash restore all goes well until I unzip the .bat file that is needed. When unzipped it seems to change the format of the file and it won't run. I've done a search on this and have heard of other people having this problem so I know it is solvable, but I just can't seem to get it to work.
Any help would be much appreciated.
Thanks!
deadeye,
Roebeet's original 5.0.0 thread in Developer Forum has a bunch of info as well as several links to posts others of us have put together about dealing with this problem.
There also is another post near the top of Developer I put together on the USB .zip files needed and where to get them.
And I know I have written a bunch of help messages with detailed info to other
folks with your problem.
Check these out and let us know if you have questions. I'm sure it can be brought back, but may take some research and learning.
Rev

Thanks for your response!!!

[Q] Rhodium210

Okay, I have successfully installed the latest build of xdandroid on my touch pro 2 phone.. Everything's working fine..but I am experiencing a problem, which I have never encountered before.. Every-time I try to turn on the wifi feature, I get "Error" and nothing else I have done has actually fixed this annoyance.
I've read in the correct development thread about this, and someone posted a fix.. But due to lack of information, I am not understanding what else I need to do..
"Well for one, you can do the wifi-nvram trick semi-automatically - just put the file on your SD card and symlink (ln -s) it to the correct location in /data."
Basically, I've reached the part of downloading the txt file, replaced the x's with my phone's mac address, then placed the file on the root of my sd card.. The rest, I have no idea..
Can someone please explain(IN FULL DETAIL) the rest of the steps to me?
I'm bumping this thread, and will continue to do so until someone provides me with the correct answer I seek.

Infuse EFS Folder (Request for someone's backup)

Hi guys,
One miraculous day, my efs folder became corrupt, when it just so happened to be the week after the hard drive on my computer took a dump! What a week this has been.. I was wondering if it is possible for someone to zip their EFS folder and send it to me to see if I can't get this phone to connect back to the network again. I honestly think there are applications on androids marketplace that will wipe things if you have superuser installed.. because it was like BAM, one morning I wake up and my efs folder was deleted the day after I had installed some new apps.
So my question is - Will someone send me a backup of their EFS? If that won't conflict with their phone of course -- I would send it back to Samsung, but their 3rd tier support has no idea what I'm talking about - they just hear root and think I'm a piece of trash.
Any help would be greatly appreciated - I have not seen anything about trying someone elses efs so I thought it could be a bit experimental as well.. Thanks

This is an interesting request, Brett.
I thought the efs.rfs file contains one's phone imei number/network id etc.
idk for sure...
I thought using someone else's imei is kinda like "let me borrow your ss# so i can check the ss office to see if mine is working.
I didn't know if you found this link and tried it?

Fortunately for me, I had a efs backup on my hd.
I think I also saw scripts in Zeus and Doctor ROM that backs up efs also prior to flash..
good luck
I wasn't trying to steal anyone's IMEI.. I just have tried multiple techniques, but I have not tried the first link..
I've been having trouble getting a shell with adb, does it need to be in download mode?
I was trying to see if it were possible to copy someone's existing files, and use a hex editor to change things, but reading into it, the IMEI is not able to be edited easily without knowing the encyrption type.
I'm just frustrated and have been back and forth with both at&t and also samsung (Their support is a joke, no one I spoke with even knew what the EFS folder was..)
I will try this technique and will report back later when I get home from work tonight. I've been reading a lot of similar issues with the null/null IMEI in the infuses and the guy at the AT&T store said that this was the reason they stopped selling the phone in their store.
Thanks for the help, I'll let you know what happens.
-Brett
Goodluck.
From the tone of your post, I didn't suspect any malice...I had a gist of what you were trying to do.
From reading some of links, there may be some method of recovery.
I hope that you're able to get it back.
I posted one a while back. I think it was in the q&a section. I won't be at my computer for a couple of days or I'd upload it for ya. Try searching or scrolling thru there.
Edit: I just uploaded an EFS.zip, unzip and flash the included efs.tar thru Odin or heimdall.
I had the same problem but i fixed it through Odin. There is an option in odin where you can click on the side (sorry i just reformated the comp so i dont have odin installed) that says something about the EFS. Try that, it fixed it for me.
On a related note. I thought I read somewhere that typical backups such as tibu and nandroid do NOT back up the efs folder. Is this correct? Should we all be doing this manually to protect against corruption?
Try searching here or on market. I remember there was this app called "nitrality" something. This app backs up EFS that we can restore in case we mess it up.

I did try to dl that app and ran it. It didn't work for me. The app hung up the system until you fc it.
If you're versed in linux or Term emu, you can use script to back up your efs.
If you had flashed zeus or doctorz, there are scripts build in that backs up your efs.
if you had root explorer, you can find efs folder in your root. long press on the folder allows you to create zip or tar of this as well.
Any harm in just copy/paste the whole folder to external SD with root explorer? Then copy paste to windows over USB? Will permissions get messed up?
I think I've already backed it up but there have been a couple threads on this. Wonder if it should be part of superthread or a sticky...do this first :...

no problem with copy/paste that I know of.
Being cautious, I have a zip, a tar, and the whole folder on my PC, USB and box.net.
Hypothetically,
I have access to another Infuse on the same family plan at that, if i were to copy the efs folder to mine what would that do?
I want to make sure not to have the same IMEI number on the network though, but this could save me a lot of hassle...
any thoughts?
Read the threads on the links I provided...you will get more understanding.
I have multiple times, but the first post that seemed like it would be the best fix, I have to get him to send me a fixed nv_data file and he seems to be unresponsive at the moment.
I think I'm going to root the 2nd infuse, back up her efs folder (MULTIPLE times lol) and fix it so it's generic and not an exact replica of hers..
Do you see any problems there? I'm definitely not an expert at all with this.

In order to see what is on the root of a phone, you may need to root it.
Once rooted, you can look for the efs folder.
I haven't used z4root in a while on an unrooted phone, I don't know if this program will let you see the root folder or not. It's possible.
The efs on my phone shows several programs and folders.
One of the folder is /imei. I suppose this is where the unique id is located.
read the thread: http://forum.xda-developers.com/showthread.php?t=1372455
as you can see, the efs contains unique id...i'm not sure of even how to make up a different imei file from using someone else's efs folder.
if your phone boots up but does not connect, if you go to settings/about phone/status
does it list the imei?
if it does, are you able to use a script in terminal emulator to back it up?
if you can't find the script, you can try flashing doctor or zeus rom, they have scripts to back up your efs folder. then try locating it on your phone.
the other thought i had was for you to call your provider to see if they can give you your previous imei number.
I'm only reasoning from what I have read...these are new territory to me.
Right, I have rooted my phone and for whatever reason the EFS folder is completely empty... The folder is there, but completley empty.
I have the IMEI number, its on the back of the phone as well as AT&T gave it to me.
The fact that my entire folder is empty, and I hadn't backed anything up because I never flashed the kernel or rom makes me think that the android marketplace does have malicious code that simply says:
if(phone==rooted){
wipe efs foler
}
continuing to pull my hair out and attempt new things, if anyone has any ideas let me know.

Check out Post # 5, I just edited my post.
its not simply a folder its actually a partition, on Linux you can mount drives/partitions however you like so it can appear to be under another directory and be an entirely different device.
you can make a .rfs image from the dd command through adb or terminal emulator.
if it is corrupt you "may" be able to salvage it through options of the dd command.
I gotta look up the device path and whatnot but if there is anything on there, visable or not, you might be able to recover the unique files and paste them over the files from someone else's efs backup. if not I have heard but never tried it, but I heard that fromatting the partition will cause the system to generate a generic efs, but I don't know for sure.
edit: the device location is /dev/block/stl3
you can dump it to the SD card with
dd if=/dev/block/stl3 of=/sdcard/efs.rfs bs=4096
if there are bad blocks I think but not quite sure you can add noerror to the end
dd if=/dev/block/stl3 of=/sdcard/efs.rfs bs=4096 noerror
but if the information has actually been deleted unless it was overwritten it is mostly intact. it is not well known that delete doesn't actually delete the data, even after a format data can be recovered with the right program. if the dumps come up empty there is also dd_rescue and foremost but I don't know if those commands are available on android, but you may be able to loop mount the dump on a Linux box or in cygwin and try the ddrescue or foremost commands.
http://www.linuxquestions.org/questions/linux-newbie-8/learn-the-dd-command-362506/
hopefully you can recover something. and learn something along the way. this is also useful for recovering deleted files and securely deleting stuff you want gone for real.
i remember I lost my efs on my captivate. There are tools in the forum to get it back.

[Q] CWM recovery filenames

This is a general CWM question but I could not find any place better to post on XDA, so excuse this if incorrect location.
I have flashed all the Skyrocket ICS roms in the past few days to see which I liked best. Before I flashed a new one, I would make a CWM backup of the current one. Wanting to easily be able to identify the files, I appended the rom name to the end of the CWM filenames after deleting all the characters after the date, which appeared to be a GMT time stamp. Now, when I try to restore any of those files, I get an MD5 checksum error. I am only assuming that this is due to changing the filename and not some other problem. Anyone have any ideas on how to fix this? TIA.

Are you talking about the folder name? Because that shouldnt affect it. Inside the folder that is created for each backup, there are backup files which dont have any dates/times in the filename itself.
I vaguely remember reading about this, but I can't recall how it was resolved. Try updating your can to 5.5.0.4 Touch or 5.8.1.3 (?? something along those lines) and seeing if that resolves it. Outside if that I must ask the obvious, did u Google "md5 checksum error cwm"?
Are you using the same CWM version as you did when you backed up? If you didnt, then thats one reason. You have to stay on the same CWM version, many of these CWM versions floating around have different fixes in there.
One way around this is to go to Advanced Restore and restore all the IMG files from there.

I figured I would post this fix here in case anyone else ran into this problem. This is assuming you did not change the folder names and let Clockworkmod create them. I haven't had it happen until today, but it's not a nice message to see when you are trying to do a restore.
Code:
Checking MD5 sums...
MD5 mismatch!
Do this to fix:
To fix this problem use the code below. Substitute the final folder name for the backup you need to fix.
Code:
adb shell
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53
# rm nandroid.md5
# md5sum *img > nandroid.md5
When that finishes, re-run the restore and everything should be fine.
NOTE: As rpearl stated, there could be something really wrong with your nandroid, so use this tutorial as a learning experience and not a fix-all. In my case, everything was fine after restoring. However, that may not always be the case. Do this with caution.

That is correct on most of them. I updated to CWM Touch for the last one, but it did not restore either. To check this out, I just did a backup and without changing the name did a restore and it worked fine. The thing that was odd in the backups that would not restore was that it immediately bombed out of the checksum each time as if it was checking the name itself first.
That is brilliant. I did not realize you could generate the MD5 from ADB and stick it right into the folder. Thanks!
The few times this md5 mis-match has happened to me was because (a) the backup was actually messed up (check folder size) probably due to corruption or (b) my SD card was out of space. I've always renamed my backup set similar to yours (I append the ROM name) and it never affects the restore.

Are you using touch or standard CWM? I wonder if this only happens in touch version. I will try this in the next few days.
I changed the name of one of the backups I created with CWM touch and it restored fine using touch. I suppose my earlier problem may have been trying to restore a backup created with old CWM using touch version.
well since you are on the subject cwm touch im making a nanadroid backup of my current ics rom right now as i speak. i started about an hour ago and its still on the backing up data part. when i used the older version to make backups i dont remember it taking this long. have any of you had cwm touch take well its been a little over an hour now? i do have more apps on my phone now than i did the last time i made a backup would that matter? should i just jerk the battery out and go back to the older version of cwm i was using? thanks ahead of time for any advice / help you may give i would appreciate it. im trying to backup this rom cause i want to flash a different modem cause the ics modem form the leak is crap and need a backup in case it dont work..

If you are using sk8erwitskil version of the CWM touch (ClockworkMod TOUCH 5.5.0.4 v3.5) then most likely you didnt follow one of the directions on the front page. This is a known issue. Here it is again. You need to create that file on the location you backing upto.
For CWM to recognize the .hidenandroidprogress file you need to boot into CWM and go to mounts and storage>>mount /sdcard then go back to backup & restore and make a restore and it should work everytime (as long as you do the steps in that order and you have the .hidenandroidprogress file in /sdcard/clockworkmod & /sdcard/external_sd/clockworkmod folders)
There is a known bug in ClockworkMod 5.5.0.4 that long file names can POSSIBLY cause backups to hang. There is a solution/workaround:
•boot into recovery
•try to make a backup (no matter if it passes or fails proceed to next step)
•either through terminal emulator or through adb run the following command EXACTLY:
Code:
touch /sdcard/clockworkmod/.hidenandroidprogress
•if you are backing up to external sdcard then run the following:
Code:
touch /sdcard/external_sd/clockworkmod/.hidenandroidprogress

Not sure, I used that for awhile but then went back to the other touch and Ive had those two files still in my directories.
I would go ahead and create those two files (one for internal SD and one for external SD if you got one you are using that is) and try it again. Make sure you call that file exactly the way it is, or copy/paste the code identically if you do it through ADB.

Well the crazy thing is after sitting there over an hour waiting I finally took out the battery and even though it never said complete all the files are there but I still don't trust that it made a good backup so I deleted those files tried putting in the code above and it still would not work so I flashed back to version 5.0.2.0 thats not touch and it made a perfect backup in under 2 minutes. Might be one of those it just ain't gonna work right on this specific phone thing or it could be the little green gremlins at it again lol... who knows.. I'll just wait for new version of touch to come along and try it. It won't be long till a newer greater version comes along as fast as technology is going today.. thanks for the help. I'm learning more and more each day from you guys on xda.....

Not sure if this is the cause of the issue but for nandroid backups you can't make a folder name with spaces otherwise you will get an md5 sum error. Try renaming the folder with underscores instead of spaces

[Q] two storage locations maybe?

I don't even have any idea how to search for this or even ask about it. I'll try!
Okay, so after having trouble with 4.2.2, I decided to flash an older rom. I had some problems with wifi logo turning white and not being able to connect to Google, so I searched for a new gapps to flash. I was having computer trouble, so I downloaded it onto my phone, it saved to the downloads folder. I also had noticed none of my other files were in there, which kinda freaked me out, but the same amount of space was being used on my internal memory (I don't have a SD card). Anyway, I went to go flash it with twrp and went to downloads and saw all my OLD files, which didn't include the new gapps download. So, I went to root explorer after rebooting and moved the gapps to my root folder, then restarted to recovery and it's not there. The only thing I can think of is when I'm in recovery, it just says sdcard, when I'm in the system, it says sdcard0.
Does anyone know what's going on and maybe something I can search for? This is weird. My files are clearly there and I just can't access them... even with full root access!
Sorry if this didn't make a lot of sense, I have no idea what's going on at all and I'm also kinda tired. Hope you can help!
------ I found the answer here: androidforums .... /verizon-galaxy-nexus-all-things-root/649940-4-2-sdcard-sdcard-0-observation.html
My tired brain finally kicked in and I searched sdcard0 and figured it out. Now, I guess I have to move stuff so I can use the old os. I'm only not deleting the post because it might helps someone. And I'm sure modifying links isn't allowed but I can't link with less than 10 posts and I wanna make sure people get the answer, so... yeah... Add com in the middle.
